AFAIK emergency vehicles do not reply on mobile telephones.

Wrong again Terry. Our fire vehicles have an inbuilt hands-free mobile
phone. Put there by FESA.

Wow. You get that much coverage? It'd be utterly useless with our
RFS.

That ******* communication authority wouldn't allow us to renew our
VHF license when the beancounters let it laps a few month. VHF was
the only practical and reliable means of contacting all the techs for
the entire duration of their trip home. But UHF is the way of the
future, man. Like 3G. And those 3G aerials on cars are such fashion
statements.

It typically takes 25-30 gallons of petrol/diesel to fully-consume an
average-sized body under ideal conditions. That I am conversant with
this level of detail should serve as an indication of why the wise man
does not ask me questions about MS-Windows. --Tanuki on ASR

A driver ON the phone is far less dangerous than a driver looking at
the phone, pushing buttons, trying to work out why his call just
dropped out.

Maybe you could work out something (with frequency Doppler-shift? :-
P ), so it doesn't do anything unless the offending phone is moving
away from the jammer. That way you could be pretty sure the resulting
distracted driver doesn't run you over.

Our local coverage is much better since we got 3G, especially with a vehicle
arial. We have a few hills and valleys and radio reception is iffy, when it
works at all. The phone is used for personal messages and stuff like
'someone is injured'.
